Setup: Click on Measure.Change the Gravity to 10 m/s².

1. Place the skater on the track. Pause the skater at the point of your choice and place the purple Energy measuring tool on the point beneath the skater. The point will be highlighted in yellow.

1. Use the measured height to calculate the potential energy - use an equation from our textbook (include a page #). Your value should be close to the given energy value. Explain and show your work below.
